SAMUEL II. IIAAS, OF PHILADELPHIA; PENNSYLVANIA.

CHECK-HOOK.

SPEGIFICATION forming part of Letters Patent No. 400,332, dated March 26', 1889.

Application filed June 23, 1888; Serial No. 277,977. (No niodl.)

To all whom it may concern.-

Be it known that I, SAMUEL H. HAAS, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Check-Line Hooks and Terrets, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a check-line hook and terret formed of stationary and movable jaws and means for holding said jaws in contact, the construction being hereinafter fully set forth.

It also consists of a novel manner of connecting the jaws, as will be hereinafter fully set forth.

Figures 1 and 4 represent partial side elevations and partial vertical sections of checkline hooks and terrets embodying my invention. Fig. 2 represents a vertical section on line a: ac, Fig. 1. Fig. 3 represents a horizontal section on line 1 y, Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A represents the stationary jaw, and B the movable jaw, of the check-line hook and terret embodying my invention.

The jaw B is pivoted to the plate 0 above the base D of the device, said plate being bifurcated, as at a a, to receive an extension or heel, E, of the movable jaw. Interposed between the rear of said heel E and plate 0 isa spring, F, which presses upwardly against the jaw, and serves to force the nose I) of said jaw against the nose Z) of the stationary jaw A, thus olosin g the jaws. In the lower wall of the plate 0 is a pocket, G, which receives a portionof the spring F, so that a long and powerful spring may be employed without increasing the dimensions of the plate and heel.

It will be seen that when the jaw B is forced backwardly downwardly the jaws are opened, whereby a strap or line may be passed between them, and thus connected with the stationary jaw. In the motion of the jaw B the heel E plays between the walls of the bi furcation of the plate 0 and compresses the spring F. Vhen the movable jaw is let go, it

immediately returns to its normal or closed position, so that the strap or line is prevented from displacement. The jaws maybe readily opened when it is desired to withdraw the strap or line. The plate 0 is formed with or secured to a post, H, which passes through the base D of the stationary hook, and has at its lower end a stem, H, which is screw-threaded for engagement of a nut, J, the portion of the post above the base having a shoulder, K, which abuts against the base. When the stem is passed through the proper part, c, of the harness, the nut J is screwed in position, whereby the leather or harness is compressed between the base D and the nut J, so that the device is firmlysupported and the post is immovably retained on the base. By this construction the strength of the parts are increased, as the post may be made heavier and stronger and is not liable to break off at the base when struck or strained. The bifurcation a of the plate incloses the heel E of the movable jaw, and thus protects the axial portion thereof from being strained or broken in lateral directions. Furthermore the jaws may be disconnected when the nut is unscrewed and the post withdrawn, whereby the parts may be packed in small compass.

For convenience of operating the movable jaw the same is extended rearward of its pivot, forming a handle, as at B.

The contact-faces of the noses of the jaws are flaring, so as to permit the convenient passage of the strap or line past said faces during the application or removal of the same.

I am aware that it is not new to secure the movable jaw of a check hook and terret to the stationary hook thereof by means of a support having a screw end; neither is it new to provide the movable jaw which is pivoted with a spring for keeping the same in closed position; but I am not aware thatit is old to form a check hook and terret, as herein described and claimed, wherein the movable jaw is so pivoted and arranged relatively to the stationary jaw that when the jaws are in contact the movable jaw is approximately in horizontal position, and the noses ofboth jaws are flaring from the point of contact, the securing-plate, to which the heel of the movable jaw is secured, being bifurcated and recessed, as shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A combined cheek hook and terret having a stationary jaw, a post stepped in said stationary jaw, a plate secured to said post and having a recess therein, a movable jaw with heel pivoted to said plate, a spring in said recess bearing against said heel, and a nut working on a screw-threaded lower end of said post, said parts combined substantially as described 2. The combined check hook and terret herein described, consisting of the stationary jaw A, with nose I), and movable jaw with hose Z) and heel E, the bifurcated plate C, having recess G, the post ll, stepped in jaw A, and the spring F, the said heel E being pivoted to plate G,a11d the spring F being seated in recess G and bearing against the heel E, and the said movable jaw being substantially in horizontal position when closed, said parts bein combined substantially as described.

3. In a check hook and terret, a movable jaw with a removable supporting-post having the shoulder K and screwstem H, in combination with a stationary jaw having an opening in its base portion, said stem being adapted to pass through said opening in base and por tion of harness attached, and secured thereto by a nut on said stem below said harness, substantially as and for the purpose set forth.

i. A combined check hook and terret consisting of a fixed jaw with base having opening therein, a movable jaw with heel, abifur cated plate with recess, a sprin g seated in said recess and bearing against the said heel, a supporting post for said plate having the shoulder K and screw H passing through the base of said fixed jaw, and a nut adapted to work on screw-stem, said parts being com bined substantially as described.
